Hi there everyone, this is a 2003 Sentra 1.8 Engine cold air blows the first thing we did was replace the thermostat and flush the heater core, still there was not heat, when we check the hoses that go to the heater core through the fire wall, one was hot and the other was cold. I guess this indicates clogged heater even if we try to flush, what do you suggest.
thank you

Sounds like you're on the right track. If flushing doesn't work, replacing it is the next step.

Make sure you did a good job on the flushing. I usually disconnect both hoses and attach a 2 or 3 foot hose to the core. You could even pour a little CLR into the hose and let is sit in the core for a little while and then use a garden hose to blast it clear in both directions.

Question OP? > If you can get some water to flow thru it now for flushing it would give some heat at least not NONE. None to me means a different problem IF YOU HAD SOME FLOW + one side hot and cold is possibly just hot air going thru which won't blow warm air into the car - take liquid.
If so (air in system) that is either it isn't full inside radiator and engine -- reason can even be a bad radiator cap, didn't fill it properly, exhaust gasses getting into cooling system higher or the list than just needing a new core AGAIN IF IT FLOWED AT ALL WHILE FLUSHING,

IDK how much real flow goes thru this one now.
Heater core appears like most with end tanks. If it (many) are used at a by-pass as well then engine should be having problems more than "lack of heat" IMO.
What could stop one all at once if so if OP observed this is use of a sealer and that should have been noticed when replacing thermostat. We (most all of us) suggest against use of that ever but it sure sells well out there,
